[Xsltforms-support] how can I get the query string parameters in xforms

[Mathias P. <Mat...@gm...>]

I want to dynamically load my instance data, using something like 

http://example.com/xforms/EditorTypeA?instance=id401

I searched, but there does not seem to be an xforms way to do this, so
what would be a portable javascript way be? 

Putting the parameter value in something like a currentDocument instance
on load and then use a replacing submission using that instance value on
xforms-ready??

If that's the way, this could probably be generalized to generate a
simple xml instance from any query string
(<querystring><paramX>valueX</paramX></querystring>), does something
like that exist?

Thx for any help,

Mathias

The XForms 1.1 proposed recommendation says : "The |resource| element 
allows the URI used for a submission to be dynamically calculated based 
on instance data."

This is implemented in XSLTForms and verified according to Test 11.6.1.a 
of the W3C Test Suite.

Alain,

I can't find a way to get at the document uri. Can you give me an example? 
I tried with document-uri, but that's not there. Anyway, I do not even know if 
I even think along the right lines, so I'll ask.

Is the general idea of

<xf:submission ... >
<xf:resource value=(substring-after(document-uri(instance(??), '?')) />
</xf:submission>    ^^^^^^^^^^^^^^^                       ^^ 
		    this is obviously only a first shot   Which instance??

correct?

Any hints or tips?

Thanks, Mathias

fn:document-uri(node) is an XPath 2.0 function and its support could be 
added in XSLTForms...

You can try to define it yourself in Javascript this way :

<script type="text/javascript">//<![CDATA[

XPathCoreFunctions["fn:document-uri"]= new XPathFunction(false, 
XPathFunction.DEFAULT_NONE, false,
        function(node) {
            ...
            });

//]]></script>

Yes, this should look like this.

Orbeon is the only XForms implementation supporting XPath 2.0 and it 
would be a good idea to analyze its behavior according to the node 
parameter. Depending whether the instance is embedded or loaded 
externally, the return value should be different...
